How to use the email signature generator

  1. Fill in the fields you want to appear; leave the rest blank.
  2. Choose an accent colour and where a photo should sit.
  3. Copy the rendered preview into your client's signature box, or take the HTML.

About this tool

This produces a signature as a table with every style written inline on the element. That looks like markup from 2003, and it is deliberate: Outlook on Windows renders email with Microsoft Word's layout engine, which supports neither flexbox nor grid, and several clients strip `<style>` blocks before display. Anything that must survive has to be an attribute on the element itself.

Every value you type is escaped before it reaches the HTML, and every link is checked before it becomes an href. A `javascript:` or `data:` URL in the website field produces plain text rather than a link — signatures get forwarded, and markup that carries a script into someone else's inbox is not something a generator should be able to produce by accident.

A plain text version is generated alongside, because a well-formed email carries both. Some clients display the text part, some recipients have HTML off, and screen readers generally get a better result from it. Most signature tools omit it entirely.

There is no tracking pixel, and there is no hosted image. Both are standard in commercial signature generators, and both mean every email you send reports back to a third party — including the ones you send to your doctor and your lawyer. If you add a photo it is your own URL, served from wherever you already host it.

Common uses

  • Making a consistent signature for a small team.
  • Replacing a signature that breaks in Outlook.
  • Producing both HTML and plain text versions of a footer.

Frequently asked questions

Why does the HTML use tables?
Because Outlook on Windows renders email with Word's layout engine, which supports neither flexbox nor grid. Tables with inline styles are the only layout every client agrees on.
How do I install the signature?
Paste the rendered preview — not the HTML source — into your client's signature box. Most clients accept pasted rich text and keep the inline styles.
Does it add a tracking pixel?
No, and it never will. Commercial signature tools commonly do, which means every email you send reports back to a third party.
